Hi, Can anyone confirm if this is a standard design issue or is my device faulty? I am just about to leave to have it replaced but dont want to exchange it if its gonna be the same on the new one. Its pretty much perfect in every other way with the exception of this flicker on the lowest brightness setting. i have tried turning off auto brightness and resetting the device but none of these resolve the issue. Mainly apparent when on bettery at about 90% charge (ish) Very apparent when loading a page it safari, its looks quite terrible and shows a lot of flicker during these times... Any advice before i shoot off?
